I think it could be useful to change the optics a little bit. Instead of seeing it as a purely gender-based issue, it would be interesting to also see it through the intersection of gender and criminality, as well as the associated biases and more.
Some things that come to mind in this respect:
- Men are more likely to become suspects in the first place
This is beautifully illustrated in this answer. In essence, we don't have statistics on crimes committed; we have statistics on cases closed. Using this statistic (which states men are most common offenders), police is more likely to see men as potential offenders, and as a result, sentence men more. This is reflected in the crime statistics and...you get the idea.
- Men are more likely to be victims of violent crimes, physical abuse, and bullying with physical elements, prompting them to develop more aggressive defense mechanisms
Such victims can often overreact on perceived dangers, causing trouble and sending them through the loop of stirring and thereby expecting more aggression. As a response to physical dangers, men often develop high physical strength (making their response more dangerous) and higher levels of testosterone (contributing to aggression). This is also projected onto a much larger group of men - many boys are preemptively taught to "stand up to bullies" (not by exposing and reporting them, but through the same aggressive defense), sending even those otherwise unaffected through the same loop.
Outside of this particular scope:
- Men have much less freedom of healthy emotional expression
Pretty much the only socially allowed negative emotion a man can have is aggression. Men expressing sadness, grief, fear are often seen as "weak", "disgusting", their feelings are invalidated, they are said they're not "real men". Eventually, all these emotions turn to anger, which is considered acceptable. Left without proper venting, the person can become danger to others.
- Men have more impulsive sexual behavior
Male sexual drive is more pronounced compared to female one. Lack of sexual satisfaction can be particularly dangerous, clouding healthy judgment in certain individuals. Unlike women, who can channel this into sexual work and other outlets, men are relatively rarely presented such opportunity. This leads to elevated rates of sexual offenses.
